Tính:(0.25)3.32;(-0.125)3.804
tính:
a. (0.25)3 . 32
b. (0.125)3 . 804
so sánh \((0.25)^4 \) và \((0.75)^{3}\)
a)|x-3,5|+|4.5-x|=0
b)(x-3)2=0.25
c)(2x-1.5)3=|(-0.27)
d)3.2x+(-1.2)x+2,7=(_4,9)
Tính \(A=\left(0.25\right)^{-1}.\left(\dfrac{1}{4}\right)^{-2}.\left(\dfrac{4}{3}\right)^{-2}.\left(\dfrac{5}{4}\right)^{-1}.\left(\dfrac{2}{3}\right)^{-3}\)
A=[(3/11+1-3/7)/(3+9/11-9/7)]-[(1/3+0.25-1/5+0.125)/(7/6+7/8-0.7+7/16)]
B=1/3+1/6*(1+2)+1/9(1+2+3)+...+1/6045*(1+2+3+..+2015)

Tính giá trị của biểu thức: \(A=\left(\frac{\frac{3}{7}+\frac{3}{11}-\frac{3}{13}}{\frac{5}{7}+\frac{5}{11}-\frac{5}{13}}+\frac{0.5+\frac{1}{3}-0.25}{\frac{5}{12}-\frac{5}{6}-\frac{5}{9}}\right):\frac{2016}{2017}\)
Thực hiện phép tính: \(A=2010.\left(\frac{\frac{1}{6}+0.25-\frac{1}{8}}{1+1\frac{1}{2}-\frac{3}{4}}+\frac{0.4-\frac{2}{9}+\frac{2}{11}}{3-\frac{15}{9}+1\frac{4}{11}}\right)\)
A= [(-3/5 + 4/9):2/7-(-14/9+2/5):2/7]:(32/7.71/2-32/7.51/2)
